VALVE MECHANISM FOR STEAM-CARRIAGE BURNERS.

SPECIFICATION forming part of Letters Patent No. 707,478, dated August 19, 1902.

Application filed April 19, 1901. Serial No. 56,542. (No model.)

To all whom it may concern.-

Be it known that I, RoLLIN H. WHITE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Valve Mechanism for Steam-Carriage Burners, of which the following is a full, clear, and exact description, reference being had to the accompanying drawlngs.

Fluid fuel is used on nearly all steam-carriages. Such carriages usually, if not always, have a main burner for heating the generator and a pilot-burner for igniting the main burner.

The object of my invention is to provide novel means for controlling the flow of fuel to the main burner. It is desirable that a valve which controls such flow shall be operable either by a person standing on the ground, but stooping down, so as to be able to look beneath the carriage and see the burner, or by a driver sitting on the seat of the carriage. It is also desirable to provide means for automatically controlling the flow of the fuel, to the end that the heat from the burner shall be automatically regulated in accordance with demand for steam, and it is also desirable to make the mechanism as simple and inexpensive as possible. The invention relates to the valve mechanism whereby these results are attained; and it consists in the construction and combination of parts hereinafter described and claimed.

In the drawings, Figure 1 is a plan view, partly in section, of the mechanism embodying my invention. Fig. 2 is a side elevation of a steam-carriage and my invention applied thereto. Fig. 3 is a front elevation of a part of the said mechanism, and Fig. 4 is a vertical sectional view of the valve-casing and some associated parts.

Referring to the parts by letters, A represents a valve-casing having, as shown, the following construction, viz: It has a vertical tube a and a horizontal tube a, crossing the lower end of said vertical tube and integral with it. This horizontal tube terminates at one end in a discharge-nozzle a and contains a valve-seat located between said discharge-nozzle and the point at which the combustible is admitted to said tube a'-viz., the point where the tube a connects with it. The tube a also contains a valve-seat a and the combustible which has been previously Vaporized is admitted to the tube a above said valve-seat through an inlet-opening a which is connected with a supply-tank. In the vertical tube is a valve B, whose lower end is fitted to the valve-seat a and the valve is moved by gravity preferably against said seat. On one side of the tube a of valvecasing is a housing a", in which a bell-crank lever D is pivoted. The substantially horizontal arm (1 of this lever engages beneath collar 1), which is adjustably secured to by being screwed upon the stem of the valve B. There is a hole in the top of the tube a, through which the valve B may be introduced, and this hole is closed by a screw-plug a. The vertical arm (1 of this lever is engaged by an endwisemovable horizontal rod 1), which enters said housing. As shown, this rod is a part of a thermostat P,the specific construction of which is described and claimed in the Ruud patent, No. 610,281. The means for fastening the outer tube of this thermostat are specifically new and consist of a plate T, which is secured to the valve-casing, so as to close the open end of the housing 0, ,which plate has an external boss twith a hole through it and a concentric rabbet t on the inner face of this plate. The tube 1) of the thermostat passes through the hole in this plate and has an external flange 1), which lies on said rabbet and is held by a screw-plug 25 through which the rod 1)" passes. This thermostat is inclosed in a tu be U, through which the steam passes.

In the tube a is a horizontal valve E, which is screwed into it and is moved against or from its seat a" by turning it. The valvestem 6 extends out of said tube a through a stutling-box (t on its end.

G represents a bracket having a wing y, by which it may be secured to the under side of one of the lower-frame members on one side of the vehicle-body F. This bracket has a horizontal sleeve g", in which a valve-operating shaft II is rotatably mounted. This operatingshaft might be in axial alinement with the valve-stem 6; but because of the mechanism connecting said shaft with the valve-stem it is not necessary that it should be. The connection J between this shaft and valve-stem c is a universal joint, the link J of which is pivotally connected with the said shaft and valvestem by pivots which are at right angles to each other. The pivot-pinsj, which connect one of these partsviz., shaft or valve-stern e-with the link pass through longitudinal slots j in the links, whereby the two parts so connected may telescope, and thereby permit the connection between said valve-stem and shaft to lengthen or shorten as the valvestem is turned. This is necessary because the shaft H does not have any endwise movement in its fixed bearing, while the valvestem 6 does move endwise as it is turned. The shaft H has at its outer end an operatinghandle (wheel) h, which may obviously be operated bya person standing on the ground and stooping down, so as to look beneath the carriage. The bracket G has also a vertical sleeve in which a vertical shaft K is rotatably mounted. This shaft has secured to its lower end a bevel-gear ls, which meshes with a bevel-gear h, fixed to the shaft II. This shaft has at its upper end an operatinghandle (wheel) ls, which handle is located above the seat F and near the right side thereof, whereby it may be easily grasped and turned by the driver sitting on the said seat.

In firing up the machine the operator will naturally be on the ground, and he will open the burner-valve E by taking hold of the wheel h and turning it. \Vhen the driver is sitting upon the seat and desires to shut the main-burner valve, he may do so by grasping and turning the wheel 1:. If, therefore, it is desirable that the burner be turned off or on when the vehicle is temporarily stopped or left, the driver may do so without getting out of the carriage. It is never necessary for him to leave his seat and stoop down or reach under the carriage to operate the mainburner valve, nor is it necessary for a person in firing up to stand up and reach up above the seat for the handle it.

Having described my invention, I clairn 1. A valve-casing having an inlet-opening, a discharge-nozzle, and a valve-seat between them, and a valve having a screw-threaded connection with said casing, combined with a bracket having two integral bearing-sleeves, two shafts respectively mounted in said sleeves, intermeshing bevel-gears secured to said two shafts, and operative connection between one of said shafts and said valves, substantially as specified.
